  2. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Linearly polarized waves consist of photons that are in a superposition of right and left circularly polarized states, with equal amplitude and phases synchronized to give oscillation in a plane. [8] Polarization is an important parameter in areas of science dealing with transverse waves, such as optics , seismology , radio , and microwaves .

  3. Plane of polarization - Wikipedia

    en.wikipedia.org/wiki/Plane_of_polarization

    For light and other electromagnetic radiation, the plane of polarization is the plane spanned by the direction of propagation and either the electric vector or the magnetic vector, depending on the convention. It can be defined for polarized light, remains fixed in space for linearly-polarized light, and undergoes axial rotation for circularly ...

  4. Persol - Wikipedia

    en.wikipedia.org/wiki/Persol

    Persol is an Italian eyewear brand specializing in the manufacturing of sunglasses and optical frames. It is one of the oldest eyewear companies in the world and is owned by the Luxottica group. The name is derived from the Italian per il sole, meaning "for the sun". Formed in 1917 by Giuseppe Ratti, Persol originally catered to pilots and ...

  5. Polarizability - Wikipedia

    en.wikipedia.org/wiki/Polarizability

    Polarizability. Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. It is a property of particles with an electric charge. When subject to an electric field, the negatively charged electrons and positively charged atomic nuclei ...

  6. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    Circularly polarized light can be converted into linearly polarized light by passing it through a quarter-waveplate. Passing linearly polarized light through a quarter-waveplate with its axes at 45° to its polarization axis will convert it to circular polarization. In fact, this is the most common way of producing circular polarization in ...

  7. Polarizer - Wikipedia

    en.wikipedia.org/wiki/Polarizer

    There are several ways to create circularly polarized light, the cheapest and most common involves placing a quarter-wave plate after a linear polarizer and directing unpolarized light through the linear polarizer. The linearly polarized light leaving the linear polarizer is transformed into circularly polarized light by the quarter wave plate.
